Design and synthesis of polyoxovanadate-based framework for efficient dye degradation

Mn-doped FeOOH modified g-C3N4 as a 3D tubular heterogeneous catalyst for photo-Fenton removal of organic pollutants

“…[12][13][14] Photocatalysis is a green, environmentally friendly and highly efficient technology for treating wastewater. 15 For example, Q. Tang, et al prepared 3D porous foam-like C 3 N 4 (F-C 3 N 4 ) by thermal polycondensation, which showed a shorter average lifetime of photoexcited charge carriers and a stronger photocurrent response. 16 Y. Li, et al used CoFeO QDs in combination with g-C 3 N 4 to form CoFeO QDs/g-C 3 N 4 , which could degrade organic contaminants as efficient and stable photo-Fenton catalysts.…”

Modulating the Catalytic Properties of Polyoxovanadates with Transition-Metal-Complex Units for Selective Oxidation of Sulfides

“…Unlike V 2 O 5 with an extended nanosheet structure, polyoxovanadates (POVs) are discrete molecular entities built of V–O units. − These cluster-type species have received much interest as catalysts for a wide range of oxidation reactions, that of sulfides included, as their molecular nature may help mitigate the unwanted overactivity as shown by V 2 O 5 . Indeed, SOS to sulfoxides was demonstrated with the use of POVs such as K 6 H­[V V 17 V IV 12 (OH) 4 O 60 (OOC­(CH 2 ) 4 COO) 8 ]· n H 2 O and [V 8 O 12 (OH) 4 (CH 3 O) 4 (DAC) 4 ]·7CH 3 OH as catalysts.…”

Band Gap Engineering and Lattice Distortion for Synergetic Tuning Optical Properties of NaNbO3 toward Enhanced Piezo-photocatalytic Activity

“…Semiconductor photocatalysts possess remarkable potentiality to degrade these organic dyes in environmental remediation. − However, the recombination of photogenerated electrons and holes seriously hinders the efficiency of the photocatalyst. Ferroelectric materials with high spontaneous polarization can achieve superior separation of photoelectrons and holes through the built-in electric field induced by polarization (convert mechanical stress into electric energy), which are extensively employed as piezo-photocatalysts over the decomposition of organic pollutants in wastewater. − Therefore, the emerging piezo-photocatalysis, combining photocatalysis and piezocatalysis, is a promising advanced technology for remedying environmental pollution and has become one of the most active and scientific research topics over these years.…”
